Excessive here means on the order of more than 8 hours. I was wondering what are the full build times for something like the AMD SMP (2 way) based Sun 2100z? or another more modern 64 bit architecture? I want to get this down to something a little more reasonable, vs. what currently equates to an over night build. While I have some money to throw at this problem, in the guise of new hardware, I am not in a position to buy a 4 way, SCSI based system. Does any one have any recommendations and real world build times to report? Dual AMD 250 Opteron = about 1 hour build times so .. fire off nightly .. watch a Star Trek re-run. add 10 minutes to that and you have rebooted and are running fine.

My recommendation are to use the -i option for an incremental build whenever you can. If you are working a specific section of the code just build that portion while you are developing and save the complete build for when you are done for the day. Heck that is probably why it's called 'nightly'. :-) Bill rushmores.net ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

SPARC builds involve several separate kernel architectures, x86 just has 32 and 64 bit. There are significant parts of the build that are rather serial; Amdahl's law is alive and well in our builds. - Bart -- Bart Smaalders Solaris Kernel Performance [EMAIL PROTECTED] http://blogs.sun.com/barts ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

Since the guy that threw a wrench into Amdahl's law in 1988 does research at Sun. :) Though I did turn up something in a search just now that says the two are mathematically equivalent. Though, if I understand Gustafson's law correctly, you'll need to be building more kernels to be able to use that style parallelism. It's more appropriate for HPC algorithms, not building kernels. :) - Matt ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
